Filed: 1922-08-14
Abstract: 204,829. Mayrow, J. J. Aug. 14, 1922. No Patent granted (Sealing fee not paid). Floors.-The metal base of a vehicle body, to which are attached girders, cross-beams, uprights &c. for the purpose of building up a complete structure, is formed from one or more plates a having longitudinal channels or corrugations b, Fig. 1, which are provided with strengthening means to prevent spreading. In the construction shown in Fig. 1 the channels b are strengthened by the attachment thereto of flanged and corrugated gird'ers d which serve to connect the base to the underframe. The girders d may, however, be dispensed with and the channels b be directly connected to the underframe, the channels in such cases being strengthened by additional corrugations g formed in the sides or bottom of the channel, or by the provision of small cross plates m, Fig. 5, or by means of long transverse members n of the construction shown in Fig. 7, arranged above and/or below the base. The weight of the base may be reduced by cutting out portions in the least stressed parts.

Abstract: 384,355. Screw pumps. GREENFIELD, F. C., Merevale, Sutton-at-Hone, near Dartford, Kent. Aug. 5, 1931, No. 22173. [Class 110 (ii).] In a rotary pump having all the features described in Specification 342,791, comprising a number of intermeshing screws of which the helicoidal faces of the threads do not touch but are fitted with spiral springs at their peripheries, the screws, while they preferably have parallel axes, are conical, the spaces formed by the threads progressively diminishing throughout the length. The screws are provided with bearings and thrust washers and can be adjusted longitudinally as in the prior Specification. A cover 4 for the casing 1 houses bearings for the shafts, and the gear wheels, and is formed with inlets 2. A cover 14 is formed with outlets 3. The screws have their peripheries tapering longitudinally in one direction, and their cores in the opposite direction, as shown in Fig. 3. The helicoidal surfaces may be other than flat, e.g. slightly concave, to increase the thread clearances. A valve chest 20, formed in the casing 1, provides seats 21 for spring-pressed valves 23, 24 and communicates at all times with the interthread spaces by ports 25, 26. The production of an undesired high pressure in the pump is thereby prevented. The valves may be in sections 27-29 and have guide pins 30 working in guides 31, 32. A port 33 connects the valve chest with the discharge passages 3, or a pipe connection to any desired point may be employed. A screwed spindle 34 passes through a stuffing box and engages a thread in the valve guides 31, 32 so that its rotation, by hand or by any self-acting device, causes longitudinal movement of the valves to expose any desired amount of the ports 25, 26 and regulate the discharge pressure. A number of screws may be arranged around an opposite-handed central screw, and two or more such sets arranged in one or in separate casings, to deal with two or more fluids, or the present machine could be combined with one such as described in Specification 342,791.

Title: Fuel-cell system
IPC: H01M8/00
Filed: 1971-04-19
Abstract: 1309517 Fuel cells BROWN BOVERI & CO Ltd 19 April 1971 [24 Feb 1970] 22306/71 Heading H1B A fuel cell comprises a heat exchanger 2 for exchanging heat between the outgoing exhaust gas and incoming air and fuel, at least one fuel cell module 4, a nozzle 3 for introducing fuel to the module, the nozzle being so arranged that during use of the fuel cell exhaust gas flows past the nozzle 3 so that some of the exhaust gas is drawn into the module, and a catalyser 10 for receiving the exhaust gas and air leaving the module so as to burn the remaining fuel therein. Fuel, e.g. propane is fed through pipe 1 to heat exchanger 2 and nozzle 3 to a battery of solid ceramic electrolyte fuel cell modules 4. The fuel is partly consumed therein and exhaust gas flows out of the modules through pipe 5. The exhaust gas is directed past the nozzle 3 where some of it is returned to the modules on the injector principle to prevent soot forming in the modules. The remainder of the exhaust gas flows out of pipe 6 to space 7. Air is conducted to the modules from pipe 8, and heat exchanger 2. Air not consumed in modules 4 enters space 7 through outlet 9. The unconsumed air and exhaust gas mixture flows through a porous catalyser pipe 10 of an after combustion catalyser to space 11, the remaining fuel being burnt in the catalyser. The heat produced helps to maintain the working temperature of 800 C. of the fuel cell. Exhaust gas from the catalyser 10 flows through heat exchanger 2 to the atmosphere via pipe 12. A resistance heater 22 is used to raise the temperature of the catalyser on starting, it being switched off by a regulator 23 at a predetermined value. In Fig. 2 (not shown) a fuel cell having a carbonate melt electrolyte is used. The fuel is passed from the heat exchanger to a converter where it is transformed into hydrogen and other gases before being passed to the fuel cell modules. The oxygen is supplied to the heat exchanger via a nozzle past which exhaust gases flow. Thus some of the exhaust gases are returned to the fuel cell modules.

Abstract: 1,187,444. Walking toy. REMCO INDUSTRIES, Inc. 15 May, 1967, No. 22502/67. Heading A6S. A mobile toy includes a body portion 21. and leg members 25 with connected foot portions. Each foot portion is provided with an opening 28 in the bottom thereof and a traction mechanism including a traction shoe 36 mounted within the foot adjacent to the opening. A drive means e.g. an electric motor, 44 disposed within the body portion, and associated gearing and eccentrics provide an up-and-down motion of the rod 55. As rod 55 is displaced upwards, a carrier 30 pivots about pin 31 and an abutment 35 engages the traction shoe 36 and causes it to protrude through opening 28 gripping the supporting surface and moving the foot portion incrementally. As rod 55 travels on its down stroke the carrier moves back along its arcuate path and the shoe, due to the weight 40, also returns but lags behind the carrier. A spring 58 biases the carrier 30 and traction shoe 36 toward a normal retracted inoperative position.  The traction mechanism of the invention may also be applied to the body of an animate or inaminate toy to effect mobility thereof.

At its lower end the cylinder a communicates with an aircompression chamber c through ports d, air being supplied to the chamber c via a non-return valve (not shown), whilst an annular air-space f around chamber c opens to the cylinder through ports e, and to the atmosphere through a port g. Around the cylinder is the annular collector h having a discharge outlet i, and the annular chamber j<1>. On the working stroke the piston b uncovers the passages j so that the exhaust gas tangentially enters chamber j <1> and rotates therein to cause rapid evacuation of the cylinder; the exhaust gas enters collector h through the orifices k. Further movement of the piston uncovers ports d and e to admit compressed and atmospheric air, respectively, to the cylinder. The fuel injector and sparking plug are secured to the cylinder head at m and n, respectively. whilst a cooling jacket is provided at o. In a modification, a sleeve valve r, Fig. 3, operated in end direction from cam u through tappet t and rocker s, and in the other direction by a spring v, controls admission to the passages j; the injection nozzle w is carried by a plug q within the valve r whilst the sparking plug is attached at x. The invention is also applicable to four-stroke engines. The Provisional Specification describes also how entrance to the swirl chamber may be controlled by a piston valve exposed to gases in the cylinder and connected to the crank shaft so that the pressure exerted therein may be utilized. The swirl chamber may contain blades to impart swirl to the gases whilst the fuel may be supplied to the incoming air by a carburetter. A compression-relief valve or an automatic inlet valve may be used for starting purposes; the invention may be applied to compression-ignition engines.

An endless-chain conveyer consists of a plurality of link-pin type chains disposed immediately adjacent to each other in a conveyer trough to form a chain assembly which extends along the central portion of the trough, the assembly being provided with scrapers which project laterally from each side of the assembly. In one form, Fig. 4, two endless chains 1, 2 have common link-pins 7 some of which are elongated to take the scrapers which are secured in place by nuts 8. The assembly travels in a two-part casing 15, the outer ends of the scrapers being provided with antifriction collars 13. In another form, Fig. 8, two chains are provided each with its own linkpins except at the scrapers where common elongated pins are used as in Fig. 4 ; the scrapers are in one piece with a cut-out to accommodate the chains. The scrapers travel on the upper run in a trough 23 at each side of which is an inverted U-shaped channel 22, and on the lower run in a trough 25 detachable from the upper casing. The casing is made in sections, Figs. 9 and 10, and the couplings between sections are housed within the channels 22 so that the sides of the casing are smooth. The couplings each consist of two plates 27, one secured within one section of the channel 22 and one within the adjoining section of the channel, and two plates 28, one secured to each section of the trough 25, the four plates being coupled by a bolt 31 provided at each end with a lug 30 which is passed through a keyhole 29 in each plate, the bolt being afterwards turned to prevent return. The couplings thus connect the upper trough to the lower trough in addition to coupling together adjacent sections. In a further form of endless structure, Figs. 13 and 14, two short lengths of chain 33, 34 are provided between adjacent scrapers, the two parts 45 of each scraper being secured by elongated pins 37 to one end of each chain length, while the other ends of the chain lengths, which terminate in inner links 36 are fixed to an inverted U- shaped bracket 43. This latter is provided with a lug 39 which is connected by a vertical pivot 40 to a pair of embracing lugs carried by a similar bracket 38 secured, together with the scraper parts, to the first-mentioned ends of the chain lengths. The assembly is driven by a pair of sprockets, not shown, one engaging each chain length. On the sprockets engaging the ends of the lengths, they pass freely on to the next two lengths without it being necessary to remove any of the sprocket teeth.
